| titleOfInvention | Low BET ball-type manganic manganous oxide and its preparation method |
| abstract | The invention provides a low BET ball-type manganic manganous oxide and its preparation method. The preparation method of the present invention comprises: 1) a pretreatment process, adding MnS in a MnSO4 solution with concentration of 130-200g/L, removing the impurities of peroxides, then neutralizing, performing solid-liquid separation to obtain a manganese sulfate filtrate; 2) an oxidation reaction process, placing the filtrate in a reactor, keeping the temperature at 25-30 DEG C, performing spraying interface reaction in 500-1000mm of H2O on a mixed gas of oxygen and ammonia gas through spraying by a spray head, wherein the reaction is stopped until [Mn<2+>] is less than or equal to 1.5g/L, and the mole ratio of O2 and NH3 of gas is 1: 12; and 3) a finished product process, performing a solid-liquid separation on the solution after finishing the reaction, washing the solid and drying to obtain the Mn3O4 product. According to the invention, manganic manganous oxide has the advantages of narrow particle size distribution, pure phase and small impurity content, Mn% is 71.44-71.08wt%, the BET specific surface area is less than 1m<2>/g, D90 is 7.0-8.5mum, D10 is 2.6-3.2mum, D50 is 4.0-5.5mum and Dmax is 15.138mum. |
